Post by superkuhIf you really want a cell phone functionality then don't do what I
did unless you have tower access.
Your project is very cool!
I have been thinking about how to avoid being tracked by cell towers.
What I came up with is some drones that would point lasers at each
other, creating a data connection to my home computer that would not be
easily traceable because laser beams are very narrow.
I don't know about 25W home emitters helping with privacy when ham
licensing also prevents encryption, but recently I bought a cheap FM
radio emitter that was meant to be used in a car so that one could plug
an mp3 player or something into it via a jack plug and the signal would
then be received by the on board car FM radio.
I built a portable 12v power supply out of 8 AA batteries for it using
a cheap standard holder, the same place also sold a car
cigarette lighter adapter (is what the device would normally be plugged
into). The device also had an usbport to plug usb sticks into to play
music directly, and it had another port, probably some microsd thing.
Reception was terrible if I only moved a few centimeters away from it
until I noticed I could plug in an usb extension cable into that usb
port, with some cable working better and others not so much, in effect
that usb cable was an antenna. Now I could walk around the house and
probably even farther and receive pretty good stereo on an old philips
ariaz FM receiver. I had inherited that receiver because the owner
could not establish a connection with a computer to it, it seems to
need a special usb cable, and could not upload songs, but I can
record songs with it now, using the FM radio!
I'm now thinking about using two of these devices (they're very cheap
around 15 euro) and a few rtlsdr equipped laptops to create a data
connection. I have no idea how to encode the data onto stereo audio
though, and maybe I could also encrypt stuff? Maybe the signal is just
too weak to be considered harmful, I mean they sell this stuff for car
audio right? Though maybe that idea of using a short usb cable as an
antenna is too smart to get away with, especially since it broadcasts in
the FM radio spectrum, though I can choose frequencies with .1
megahertz steps and noticed that some frequencies are free, especially
the lowest and highest.
How I would then mount that stuff on a drone would be step 2.
I read about drones that are in development now that can fly for
28 minutes, avoid trees and obstacles and follow and film moving
objects, like a bicyclist or a jogger, but as far as I know they haven't
been equipped with lasers yet.

the cellphones (I'm counting 2 years and 2 months now) - its a sign
I'm at the right place ;-)
Unfortunately I haven't completely abandoned cell phones. I still
have a dumb nokia that I take with me on long trips, etc, with the
battery out. But yeah, it's a desirable goal.
It seems with just a cellphone number your privacy is already
essentially void. I stopped using them entirely, even though many
organizations just assume one can call them. Some time ago my
health care provider sent me an email telling me they would switch all
communication to their webpage (I don't use webforms or webmail, just
a native mail client) and they would start sending me no-reply
emails to tell me to go there when something new arrived. I could opt
out, no problem, just give them a call :(
